When Vivian Fenster Ehrlich left a career in publishing to become executive director of the nonprofit Dorot, 21 years ago, it had a budget of $700,000 and a staff of 24 crammed into two floors of a decrepit brownstone on West 91st Street.
Now, as she prepares to become director emerita and start a venture she isn’t ready to publicly discuss, Ehrlich is running an organization with 10 times the budget and nearly three times as many staff, working out of its own 10,000-square-foot townhouse a few blocks south.
